BACKGROUND OF THE INVENTION
Field of the Invention:
[0001] The present invention relates to an apparatus for providing additional services in a mobile terminal, and a method thereof. In particular, the present invention relates to an apparatus for enabling a call connection during or after a phone call by using information generated during the phone call of a mobile terminal, and a method thereof.
Description of the Prior Art:
[0002] With recent development in wireless communication technology, use of mobile terminals has become popular. As a result of popularization of the mobile terminals, communication service companies are currently providing various kinds of service to satisfy telephone subscribers' desire, such as a wireless Internet service, short message service (SMS), and multimedia service including screen images and moving pictures, in addition to a voice communication service without any restriction in terms of time and space.
[0003] The mobile terminal has a basic function of performing voice communication with another mobile phone or a wired telephone through a base station while moving in a mobile communication service area, and has additional functions of performing data communication, such as personal information management, and information exchange with a computer and with the Internet. Recently, new mobile terminals appearing at frequent intervals in the market provide a better performance improved by providing transmission/reception of screen images or moving pictures, virtual 3-dimensional stereo sounds, Moving Picture Experts Group (MPEG) audio layer 3 (MP3) player function, and integration of camera for picture-taking.
[0004] According to functions, the mobile terminals may be classified into a terminal having an Internet function, terminal having a character transmission function, terminal having a moving picture function, terminal having a user's health check function, and terminal having a game function. Additionally, digital multimedia services, such as a digital television service or video on demand (VOD) service, have been commercialized. Some existing mobile terminals provide a 3-dimensional game function, which is more developed than a game function which uses a simple text, and a messenger function.
[0005] As described above, the technology related to the mobile terminals is being developed rapidly, and accordingly the mobile terminals are being miniaturized and provide various additional functions, such as a notepad function, phone book function, multimedia messaging service (MMS), and game function, in addition to their basic function of voice communication.
[0006] In the case that a telephone number of a third party informed by a called party's voice during a phone call is to be stored, or in the case that a call connection is required after the phone call by using the informed telephone number, a user must memorize or take a note of the telephone number during the phone call, so that the user can store or call the telephone number after the phone call.
[0007] However, in the case that the user has forgotten the telephone number of the third party or has been in a difficult situation to take a note, the user may experience inconvenience in obtaining again the telephone number of the third party. Even in the case that the user has memorized the telephone number of the third party or has taken a note of the telephone number, the user may still experience inconvenience, because the user must input the telephone number of the third party to store in the mobile phone or must dial the telephone number memorized or taken on a note to make a call connection to the third party. That is, even though the user is informed with a telephone number of a third party, a call connection cannot be made immediately with the telephone number, and the user may experience inconvenience, because the telephone number must be input for a call connection or storage by memorizing the telephone number.
[0008] Accordingly, there is a need for an improved apparatus and method for enabling an input or reception of a telephone number informed during a phone call, and to enable storage of the input/received telephone number or a call connection to the telephone number in a more convenient way during or after the phone call.

[0024] In this specification, although a mobile terminal is described as an example of a mobile communication terminal for convenience in explanation, the present invention is not limited thereto. The mobile terminal according to the exemplary embodiments of the present invention is a terminal for providing a user's convenience, and preferably comprises all the information and communication equipments, such as a mobile communication terminal, mobile phone, wired/wireless telephone, smart phone, International Mobile Telecommunication 2000 (IMT-2000) terminal, and Universal Mobile Telecommunication Service (UMTS) terminal, and their applications.
[0025] Firstly, an example of a mobile terminal configuration functioning according to an exemplary embodiment of the present invention is described hereinafter.
[0026] FIG. 1 is a schematic block diagram illustrating a configuration of a mobile terminal according to an exemplary embodiment of the present invention
[0027] Referring to FIG. 1, the mobile terminal 100 according to an exemplary embodiment of the present invention preferably comprises a radio frequency (RF) processing unit 101, data processing unit 103, audio processing unit 105, key input unit 107, memory 109, control unit 111, display unit 113, DTMF detecting unit 115, and latest number processing unit 117.
[0028] The RF processing unit 101 performs voice communication, SMS and MMS communication, and other types of communications related to data communication. The RF processing unit 101 comprises an RF transmitter for upconverting and amplifying the frequency of a transmitting signal, and an RF receiver for low-noise amplifying and downconverting the frequency of a received signal.
[0029] The data processing unit 103 may comprise a means for encoding and modulating a signal transmitted by the RF processing unit 101 and a means for demodulating and decoding a signal received by the RF processing unit 101. Additionally, the data processing unit 103 may comprise a function of extracting a telephone number by voice recognition or extracting a telephone number from a character message transmitted to the mobile terminal 100. For example, the data processing unit 103 may comprise a voice recognition/extraction unit or a character recognition/extraction unit, which may separately be included in the mobile terminal.
[0030] The audio processing unit 105 plays an audio signal output by the data processing unit 103 or transmits an audio signal such as a voice input by a microphone to the data processing unit 103.
[0031] The key input unit 107 inputs number and character information, and may comprise number keys, character keys, and function keys for setting various functions. The function keys may comprise a volume key, direction keys, and keys mapped corresponding to them.
[0032] The memory 109 may comprise a program memory and a data memory. The program memory stores program modules to control general operation of the mobile terminal and application program modules to execute a call function with the latest number after a phone call by using information input during the phone call, such as a telephone number input by a user through the key input unit 107, SMS information received from the other party or from a mobile terminal of a third party, and information detected by the DTMF detecting unit 115.
[0033] The data memory stores data generated during the execution of the program modules and setup information related to the calling function with the latest number, and may comprise a database for storing the data individually.
[0034] The application program module for executing the call function with the latest number may comprise dedicated applications such as a program module for detecting input information and extracting a telephone number from the input information, a program module for identifying the extracted telephone number as the latest number, a program module for controlling the call operation by using the information identified as the latest number during or after a phone call, and a program module for providing information on the result of the call operation with the latest number.
[0035] The control unit 111 controls general operation of the mobile terminal, and controls a mode setting if a mode setting signal for the call function with the latest number is input by the key input unit 107. The control unit 111 controls the operation accordingly if input information on the call function with the latest number is generated by the key input unit 107. Additionally, the control unit 111 controls display of additional functions generated or managed according to the mode setting signal, a user data, or a guide message.
[0036] For example, the control unit 111 identifies a telephone number input through the key input unit 107 during a phone call as the latest number, and controls the enablement of a call connection by using the latest number during or after the phone call. Alternatively, if a character message is received from a called party or a third party during the phone call, the control unit 111 detects and extracts a telephone number included in the character message and identifies the telephone number as the latest number, and controls the enablement of a call connection by using the latest number during or after the phone call. Alternatively, the control unit 111 detects a DTMF signal input by a calling party or a called party during a phone call and identifies it as the latest number, and controls a call connection to be enabled by using the latest number during or after the phone call. Alternatively, the control unit 111 detects a telephone number by voice recognition of a calling party's or a called party's voice and identifies it as the latest number, and controls the enablement of a call connection by using the latest number during or after a phone call.
[0037] During a phone call with a called party, if information is received from a calling party, a called party, or a third party, the control unit 111 preferably determines activation or deactivation of a call service mode for the latest number, and then controls registration of the latest number or a call connection to the latest number included in the input information, according to the call service mode.
[0038] For example, when the call service mode for the latest number is activated, the control unit 111 identifies input information, and, if the input information is data such as a telephone number to be registered as the latest number, provides a guide message to decide whether to register and store the telephone number as the latest number, and registers and stores the latest number according to a response to the guide message.
[0039] When the call service mode for the latest number is deactivated, the control unit 111 identifies the input information, and, if the information input during a phone call is a request for an additional function, controls an operation of the additional function.
[0040] Although an example of controlling the call operation with the latest number corresponding to input information has been described above, the present invention is not limited thereto. For example, the call operation with the latest number may automatically be performed according to a call service mode setting. That is, the call operation may be performed by identifying a telephone number input by a user or received by the mobile terminal 100 as the latest number, automatically calling the latest number after a phone call, and automatically storing the telephone number after a call connection to the latest number.
[0041] The display unit 113 displays an execution or setup menu corresponding to application programs for the call function with the latest number, and displays a mode setting guide message according to the control by the control unit.
[0042] The DTMF detecting unit 115 detects a DTMF signal transmitted by a calling party or a called party, interprets the signal, and converts the signal to a telephone number.
[0043] The latest number processing unit 117 registers a telephone number input through the key input unit 107, a telephone number detected from a character message received through an SMS communication, and a telephone number detected by the DTMF detecting unit 115, as the latest number.
[0044] Referring to the mobile terminal having the above configuration, a method for registering the latest number corresponding to input information and calling the registered latest number is described hereinafter.
[0045] FIGs. 2A and 2B are flow charts illustrating an operation method of a call connection to the latest number during a phone call in a mobile terminal, according to an exemplary embodiment of the present invention.
[0046] Referring to FIGs. 2A and 2B, if a phone call is in progress between a calling party and a called party of mobile terminals at step S201, checking is performed to determine whether information is input by a calling or called party, or by another party at step S203. The information may comprise a key input of the calling party's mobile terminal, messages such as an SMS, MMS, or electronic mail received from the called party or a third party, DTMF signal received from the called party or the calling party , or the called party's voice for reciting a telephone number.
[0047] If no input information is detected in the checking step S203, the phone call is continued at step S205, and the phone call is terminated after the phone call. If input information is detected in the checking step S203, the input information is identified and a telephone number included in the input information is extracted at step S207. Extracting the telephone number comprises extracting a telephone number from a calling party's key input, extracting a telephone number from a called party's voice reciting the telephone number by using voice recognition, extracting a telephone number from a DTMF signal, extracting a telephone number contained a character message, and extracting the telephone number of a character message sender.
[0048] After extracting the telephone number, checking is performed to determine whether the phone call is terminated at step S209. If the phone call is terminated, checking is performed to determine whether the extracted telephone number is to be stored as the latest number at step S211. For example, if the phone call is terminated, a guide message is provided to decide whether the telephone number is to be stored as the latest number, and a corresponding response is awaited.
[0049] According to the checking result in step S211, if the telephone number is not stored as the latest number, checking is performed to determine whether the telephone number is to be stored as a conventional telephone number at step S219, and, if a telephone number is to be stored as the conventional telephone number, registration of the conventional telephone number is performed at step S221.
[0050] According to the checking result in step S211, if the telephone number is to be stored as the latest number, the telephone number is registered as the latest number and displayed on a screen at step S213. Subsequently, checking is performed to determine whether a call request is issued for the latest number displayed on the screen at step S215, and, if the call request is selected, a call connection is performed at step S217.
[0051] If the phone call is not terminated in step S209, checking is performed to determine whether a tripartite call service is requested at step S223. If the tripartite call service is not requested, the existing phone call is continued at step S225. If the tripartite call service is requested in step S223, the telephone number extracted in step S207 is registered as the latest number at step S227 and a call connection to the latest number is performed at step S229. Subsequently, when the call connection to the latest number has been performed, the tripartite call service is provided at step S231.
[0052] Although not illustrated in FIGs 2A and 2B, the latest number may temporarily be stored in a mobile terminal's memory for a predetermined period or may be displayed on a screen for a predetermined period. However, the latest number is preferably displayed on the screen for the predetermined period after the phone call is terminated.
[0053] FIG. 3 is a flow chart illustrating a method of registering the latest number during a phone call and calling the latest number in a mobile terminal according to another exemplary embodiment of the present invention.
[0054] Referring to FIG. 3, if a phone call is in progress between a calling party and a called party of mobile terminals at step S301, checking is performed to determine whether information is input by a calling or called party, or by another party at step S303.
[0055] If no input information is detected in the checking step S303, the phone call is continued at step S305, and the phone call is terminated afterwards. If input information is detected in the checking step S303, the input information is identified and a telephone number included in the input information is extracted at step S307. Extraction the telephone number comprises: extracting a telephone number from a calling party's key input, extracting a telephone number from a called party's voice reciting the telephone number by using voice recognition, extracting a telephone number from a DTMF signal, extraction of a telephone number contained in a character message, and extracting the telephone number of a character message sender.
[0056] The extracted telephone number is registered as the latest number at step S309. Subsequently, if a call connection is requested by a user at step 5311, a tripartite call service is provided by connecting to a mobile phone having the corresponding latest number through a call setup at step S313.
[0057] After performing the call connection for the tripartite call service at step S313, if the call is terminated at step S315, checking is performed to determine whether the registered latest number is to be stored in a telephone number list at step S317. If storage in the telephone number list is requested, the latest number in the telephone number list is stored according to predetermined storage steps at step S319. For example, if the phone call is terminated, a guide message is displayed on a screen for a user to decide whether the registered latest number is to be stored in the telephone number list, and the storage steps are performed according to a response signal to the guide message, for example, 'yes' or 'no'.
[0058] If a tripartite call is not requested by a user at step S311, and if termination of the phone call is not requested at step S321, checking is performed to determine whether a call connection using the latest number is requested at step S323. For example, if the phone call is terminated, the registered latest number is displayed on a screen, and a guide message is displayed for the user to decide whether a call connection is to be performed by using the displayed latest number.
[0059] According to the decision in step S323, if a call connection using the latest number is requested, the call connection is performed to a mobile terminal having the corresponding latest number through a call setup at step S325. After the existing phone call is terminated at step S327, the checking at step S317 is performed, and the steps of storing in the telephone number list are performed as described above.
[0060] According to the decision in step S323, if a call connection using the latest number is not requested, the checking at step S317 is preferably performed and the steps of storing in the telephone number list are performed as described above.
[0061] Although not illustrated in FIGs. 2A, 2B, and 3, according to the exemplary embodiments of the present invention, a step of automatically registering a telephone number generated during a phone call with a called party as the latest number, and a step of automatically performing a call connection by using the latest number after the phone call, may be included. Additionally, a step of automatically storing the latest number in a telephone number list may be included after the call operation using the latest number.
[0062] Additionally, a step of transmitting input/received information to a called party's mobile terminal during a phone call may be included, and the called party's mobile terminal receiving the information may operate in the same manner as the above operation method.
[0063] As described above, in the exemplary embodiments of the present invention, a telephone number may be input by an input means of a mobile terminal during a phone call with a called party, or may be received from a called party or from a third party, and a new call connection is enabled by registering the input/received telephone number as the latest number.
[0064] In the exemplary embodiments of the present invention, the latest number may be stored or transmitted by using a key input, character message, voice signal, and DTMF signal generated during a phone call between a calling party and a called party, and a user may perform a new call connection by using the latest number during or after the phone call.
[0065] As described above, an apparatus and a method for storing/calling a telephone number in a mobile terminal according to exemplary embodiments of the present invention have an advantage that a call connection may be more conveniently performed during or after a phone call by registering input/received information, such as a telephone number input by a calling party, a telephone number received from a called party, or a telephone number received from a third party, as the latest number in a state that a call connection is setup between mobile communication terminals. Another advantage is that a call connection to a third party may be performed during a phone call by using the input/received telephone number. Additionally, the input/received information may be transmitted to a called party, and thereby the called party receiving the information may register the latest number and conveniently perform a call connection to a third party. Therefore certain exemplary embodiments of the present invention may provide an improvement of users' convenience.
[0066] The invention can also be embodied as computer readable code on a computer readable recording medium.
